Solved: Wireless plug in module card vse wireless usb adapter

Opinion please: I have an hp pavilion laptop dv2000 and I am going to purchase either a wireless pc plug in module card or one that has a usb adapter.. would like opinions on which one is better for the long run.. I am looking at a Netgear one. both say compatible with windows xp which is what I have. and my router is a netgear already.
